Answer:
concentration in mmol/L = 8.97 × 10⁻¹ mmol/L
Explanation:
Given that:
the number of moles of silver(I) nitrate(AgNO3) the chemist used in preparing a solution = 269 mmol = 269 × 10⁻³ mmol
The volume of the volumetric flask = 300 mL = 300 × 10⁻³ L
In order to calculate the concentration in mmol/L of the chemist's silver(I) nitrate (AgNO3) solution , we used the formula which can be expressed as;
concentration in mmol/L = 0.8966 mmol/L
concentration in mmol/L = 8.97 × 10⁻¹ mmol/L
Answer:
Physical change because it can go back to its original form.
Explanation:
Without the cell wall, the plant cell willcollapse. Uptake of nutrients would be tough and the cell would be without any protection. Hence the plant wouldeventually die. The cell wall is composed of cellulose and gives plants rigidity, strength and structure
